service.
Use only compatible connectors with this device. Use only self-locking snap hooks or carabiners
meeting a minimum requirement of ANSI Z359.1-99. Only use connectors that are designed for each
application. Ensure that all connectors are fully closed and in the locked position. Connectors
strength must meet the 5,000 lb requirement.
All personal fall arrest systems must meet all applicable state, federal, city, OSHA and ANSI
requirements and any other regulating government body. It is the responsibility of the employer to
regulate its worker and make sure all laws are being complied with concerning this device.
This anchorage point attachment must be identified by a qualified or competent person. For fall

Swing Fall
Swing Fall Obstacle - Danger
Danger: Avoid swing falls
Max fall distance 6’
Obstruction/Deck/Floor/Ground
Do not work above anchorage point
Work Surface
Anchorage connector
Shock absorbing lanyard
2’ clearance
Consider D-ring strength
distance and deceleration
distances from shock absorbers
and make sure you obtain a
minimum 2’ clearance.
Swing fall can occur when the worker is
not directly under the anchorage point.
Avoid a swing fall by working directly
underneath your anchorage point. Swing
falls can jeopardize the clearance required
with retractable, shock absorbing
lanyards and other sub-systems of your
fall protection system. Avoid swing fall at
all circumstances. Swing falls can cause
serous injury or death.
